Amazon have also before spoken about that their is interested of Qualcomm´s Mirasoldisplay which shall be made in a factory in Taiwan in cowork with Qualcomm.

The Mirasoldisplay is an IMOD mems-based display tech which will be very power sufficient and have full color, Mirasoldisplay will be made in 7″ and 10″ and start production in 2012.

Nobody except people working at the factories under strict NDA knows what types of screens are being mass manufactured and when, Pixel Qi has been saying for many months now that their screens are being mass manufactured.

Sounds plausible. Hmm, I think this question can only be solved if someone at PVI wants to comment on their deal with Amazon. I’ll send them a mail and see if they reply.

Of course, I’d also like (badly!) to see PixelQi everywhere; but we have to consider the alternatives. Moreover, as far as I know, mass production (in the order of several millions per year) of PixelQi screens hasn’t commenced as of yet; which is a shame.

The Transflective mode FFS compares itself with is probably that Transflective LCD that Toshiba is using in the R600 laptop and that Pixel Qi has already demonstrated that they are much better than:

Again if p-Si LCD from Sharp rumor is true, I do not know if Pixel Qi cannot alao be a part of that. No reason Sharp wouldn’t want to include Pixel Qi in their next LCDs.

Translective is only one of the three modes of Pixel Qi, what about reflective mode, the one with no backlight at all. This rumor anyways, if it comes from digitimes, they have a track record of being wrong about 90% of the time. Just because Amazon is PVI’s biggest customer does not mean they necessarily use PVI’s e-ink replacement. To me the more likely extrapolation is Quanta display is making Pixel Qi for Kindle4 as Quanta display is the company who already made 2.5 million Pixel Qi displays for the OLPC project.

Some days ago I did some reading on the topic of AFFS+, as Hydis calls it nowadays. The short timeline is:

There was E-Ink Corp., founded in 1997 at MIT developing photo phoretic
displays. In ’99 They partnered with Philips to co develop the
technology, and in 2005 Philips sold there shares to the Taiwanese
company Prime View International, a subsidiary of the Yuen Foong Yu
Group.

Then there was Hyunday Electronig display technologies, founded in 1989,
patented FFS in ’98 and spun-off in 2001. The new company was called
‘Hydis’ and developed (A)FFS. In ’04 AFFS was licensed to Hitachi. Hydis
nearly went bankrupt due to ‘unprofitability’ in ’06. But investors –
among which Hynix, Korean Bank and Hyundai insurance rescued Hydis.

In ’08, Hydis and PVI merged. After the merge, PVI was dubbed “E ink
holdings”. So it basically boils down to E-Ink holdings making AFFS LCD
displays. PVI is the largest-capacity small/midsize display maker in
Taiwan, they say.

It seems, with Hydis AFFS+ technology, “Transflective mode” (like
PixelQi offers) is not needed, as they claim their solution is already
better than Transflective mode.
http://www.hydis.com/eng/04_rnd/rnd_07.asp

As the website also mentions, AFFS+ already includes technology for ‘minimizing surface reflectance’.
http://www.hydis.com/eng/04_rnd/rnd_ap_02.asp

So sure, it’s “backlight only” technology, but if it ‘beats’ (according
to them) transflective mode, it makes no sense to put transflective mode
on it.

Therefore, I’d say there’s no business case for combining the two.
They’re pretty much mutually exclusive; as I think both try to resolve
the same problem (surface reflectance) in a different way. So I think
PixelQi technology won’t improve AFFS+ that much, and the other way
around.

Of course, as always, I look forward to your comparison of both
technologies! Watch out for the PVI stand if you ever make it to a
display conference. Maybe ask Mary Lou why PixelQi’s solution is better
than AFFS+, and ask PVI why AFFS+ is better than PixelQi. Such would be
interesting! Of course, I can try it myself, but it seems Mary Lou
Jespen knows who you are, so I think there’s higher chance she’ll
respond to your inquiries than to mine.

And again, thanks for reporting!

FFS excludes PixelQi until they implement FFS into their solutions. I would bet against seeing PixelQi in the next kindle or ipad.

http://www.thegeeksclub.com/apple-iphone-6-to-use-advanced-sharps-p-si-lcd-display

Probably will Apple some years ahead use amoled displays because they are possible to be very strong in lumen light level and amoled displays can be made thinner than 1mm as both Sony and Samsung have showed two years ago on a japanese display show.

With graphene as capacitive layer on displays instead of rare earth mineral Indium which is used today in ITO=Indium-Tenn-Oxide layer on capacitive displays, amoled displays in future with a graphene layer for capacitive displays can be thinner than 1/10 of a milimeter and still very strong and totally scratch free.

PixelQi have still a market in battery charged electronic devices.

I don’t know if FFS excludes Pixel Qi also being there in the same screen, as far as I understand the basic FFS is described as backlight only technology.
